Brief Summary:
Implants have become the perfect solution for replacement of missing single teeth partial or even complete edentulism18 However the dilemma of anterior implant-supported prosthesis is still not quite solved19-21 Implant abutments are one of the esthetic influencers And concerning the material ready-made titanium abutments are considered the gold standard of all Nevertheless the esthetic properties remain doubtful Lithium disilicate ceramics have been used as implant superstructures for many years now for their combined esthetic and biomechanical properties The purpose of the present study is to evaluate the effect of using titanium implant abutment on the color of lithium disilicate crowns and the significance of masking the titanium abutments with opaque porcelain or using opaque lithium disilicate coping on the final esthetic outcome
Detailed Description:
Clinical resemblance is one the of main factors that preclude the success of any restoration The use of conventional titanium implant abutment and ceramic restoration succeeded to prevail until now New ceramic and polymer derivatives have been introduced such as hybrid ceramics PEEK and PEKK However the low mechanical properties and the ease of breakage still limited them to certain clinical situations Hybrid fixture-abutment combinations such as hybrid abutments and hybrid crowns proved to be highly efficient in the literature But the technique sensitivity and the urge of high clinical and laboratory skills are obstacles that must be taken into consideration This is the reason that finding esthetic modification of the conventional techniques seems reasonable Masking the color of the underlying abutment appears to be a simple and easily achievable solution for having a highly esthetic implant supported prosthesis
The importance of peri-implant soft tissues whether esthetically or biologically has been emphasized in literature 4 Furthermore achieving the desired esthetic outcome depends on simultaneously matching the proper esthetic criteria of the tooth and its supporting structures 5 Esthetic failures in implant dentistry can be categorized as pink-tissue failures and white-tissue failures 6 Pink esthetics include color texture and level of peri-implant tissues 7 while white esthetics include color shape and characterization of crown 3 The mode of fabrication also influences the performance of the materials where the use of press technology facilitates the construction of implant supported crowns offering precision of fit durability and esthetic materials application 11
